LEONARD JOSEPH OLOSSEY, or MONITPELIERFVERMONT.

POWERJI AMMER FRAME.

Application filed October 29, 1907.

T 0 all whom it may concern:

Be it known that I, LEONARD Josnrr-r' CLOSSEY, a citizen of the United States, and resident of Montpelier, in the county of \Yashington and State of Vermont, have invented an Improvement in PowenHammer Frames, of which the following is a speciiica tion.

My invention is an improvement in power hammer frames, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure l is a side view of the frame. Fig. 2 is a section on the line 2-2 of Fig. 1, looking in the direction of the arrow. Fig. 3 is a section on the line 33 of Fig. 1 looking in the direction of the arrow. Fig. 4 is a plan view of the top cross bar. Fig. 5 is a detail of the pawl and ratchet mechanism. Fig. 6 is a detail sectional view of the top of the shaft or post and cross bar, and Fig. 7 is a perspective view of the third or slidable cross bar.

The present embodiment of my invention comprises a base 1, supported by wheels 2,

' and provided at its center with an upright shaft 3, having rotatably journaled thereon at its top and bottom cross bars 4, each of said cross bars being provided at its ends with sockets 5 in which are received the ends of rods 6, the rods extending between the corresponding ends of the cross bars. A third cross bar 7 is slidably mounted on the shaft, the said cross bar having at its center a double bearing 8 journaled upon the shaft, and provided at each end with a substantially rectangular frame 9, sliding upon one of the rods 6 before mentioned. Each of the frames comprises ends 10 and sides 11, the ends being provided with openings through which pass the rods, and on each of the sides within the frames are journaled upper and lower grooved wheels 12 for a purpose to be presently described.

The upper member of the double bearing has projecting therefrom a box 13, in which is journaled, at right angles to the shaft 3, a drum 14, having on one end a ratchet wheel 15, engaged by a pawl 16, one of the trunnions 17 of the drum projecting outside of the box and having secured thereto a hand wheel 18. A rope 19 passes through a hole in the drum, and winds thereon, the rope passing from the drum upwardly over a pulley 20 journaled in a bracket 21 at the center Specification of Letters Patent.

Patented March 17, 1908.

SerialNo. 399,630.

cross bar 7 from the pulley 23, to which bossthe free end of the rope is secured. By rotating the hand wheel 18, the rope 19-is wound upon or unwound from the drum, thusraising and lowering the cross bar 7 on the shaft, the bar being retained in its adjusted position by the engagement of the pawl 16 with the ratchet wheel 15.

A frame comprising side bars27, connected at one end by a cross rod 28, is mounted on the movable cross bar 7, the side bars 27 of the frame being movable between the upper and lower pulleys 0f the frames 9, one side bar being arranged on each side ofthe cross bar. The sidebars 27 are arranged with their widest dimensions vertically, and the edges of the side bars are received in the grooves of the wheel. One end of the frame is provided with a U-shaped bracket 29 arranged vertically, and with a handle 30 ar ranged horizontally, as clearly shown in Fig. 1. The arms of theU-shaped bracket are provided with studs 31 extending from the free ends thereof, the free ends of the studs being connected by a cross bar 32, held in place by nuts 33 threaded on to the ends of the studs. The U shaped bracket is adapted to receive the power hammer 34, which, however, forms no part of the invention. The supply pipe 35 of the power hammer passes upward over a grooved wheel 36 secured to a shaft 37, j ournaled in a bracket 38 on the top ofthe upper cross bar, and from thence to the source of power. The bearing of theupper cross bar 4 is provided with a depression 39, and the end of the shaft 3 is provided with a similar depression 40, and a ball 41 is arranged in the recess formed by the cooperating depressions, upon Which'the said cross bar issupported.

It will be understood from the description that the power hammer is adjustable toward and from the central shaft, is rotatable with respect thereto, and is also adjustable vertically with respect thereto, and that the weight of allthe movable parts is supported by the ball at the top of the shaft or post 3. The base may be of any suitable construction, and the wheels for supporting the base may be journaled upon the ends of axles 42- secured to the said base.

I claim:

1. A power hammer frame comprising a base, a vertical shaft arranged centrally thereon, cross bars rotatably mounted on the shaft at its top and bottom, rods connecting the corresponding free ends of the cross bars, an intermediate cross bar having at its center a bearing for receiving the shaft, and at its ends bearings for receiving the rods, a pair of horizontal bars arranged on each side of the cross bar, grooved wheels supported by the intermediate cross bar and engaging the upper and lower edges of each of said horizontal bars, a yoke for supporting the hammer and connecting one end of said horizontal bars, a handle for manipulating the bars adjacent to the U-shaped bracket, a drum j ournaled on the sliding cross bar and provided at the outer end of its journal with a hand wheel, a pawl and ratchet in connection with the drum, a plurality of pulleys on the upper cross bar, a pulley at one end of the sliding cross bar, a rope connected with the drum, and extending therefrom upwardly over one of the pulleys on the top cross bar, downwardly over the pulley on the sliding cross bar, upwardly over another pulley, and downwardly to the opposite end of the sliding cross bar, said bar being provided with a boss to which the rope is connected.

2. A power hammer frame comprising a base, a vertical shaft arranged centrally thereon, cross bars rotatably mounted on the shaft at its top and bottom, rods connecting the corresponding free ends of the cross bars, an intermediate cross bar having at its center a bearing for receiving the shaft, and at its ends bearings for receiving the rods, a pair of horizontal bars arranged on each side of the cross bar, grooved wheels supported by the cross bar and engaging the upper and lower edges of each of said bars, a bracket for supporting the hammer connecting one end of said bars, a handle for manipulating the bars adjacent to the bracket, a drum journaled on the sliding cross bar and provided at its outer end with a hand wheel, and means in connection with the drum for raising and lowering the sliding cross bar.
